[arch-general] Mailing list web-settings?

[vixsomnis]

Hi, I'm trying to update some of my settings for the mailing list, but I
can't find
the settings page on list.archlinux.org. I've tried accessing my account
via the
subscription page (e.g.
https://lists.archlinux.org/listinfo/arch-general ), 
but this just sends me a security warning. 

Specifically, I'd like to disable duplicate messages (from sending) and
add my
real name.

My message to mailman at lists.archlinux.org was bounced back, which is why
I'm posting to this list.

Thank you for any advice you can lend.
